SOUND-PROOF FLOOR MATERIAL OF CONSTRUCTION

摘要

The present invention relates to a construction method for blocking noise between floors in a multistory building such as an apartment, and a soundproof structure. The construction method blocks noise between floors by using a sponge which is cheap and has excellent soundproof function. The construction method comprises providing a plurality of cells on a ceiling of a lower floor below a bottom floor separating an upper floor from the lower floor; attaching the sponge with excellent soundproofing properties to the ceiling so that the ceiling of the lower floor directly absorbs vibration and noise generated by impact transmitted from the bottom surface of the upper floor; and bonding a shock-absorbing vinyl paper to the soundproof sponge in order to absorb vibration and noise passing through the soundproof sponge to block the noise between floors while applying flexibility of the vinyl paper to absorb impact generated when the noise is blocked. The sound-absorbing sponge is bonded to the soundproof vinyl in layers to repeat sound-absorbing and sound-blocking processes to remove noise between floors at a desired level. The thickness and density of the sponge are varied according to uses of the bottom floor partitioning a floor when the sponge is bonded to the vinyl paper, and thus the sponge is controlled to be suitable for a regulation of noise between floors according to a construction state of the bottom floor.
